When a marriage has been dissolved by a decree of divorce and
either there is no right of appeal against the decree or, if there is such a
right of appeal, the time for appealing has expired without an appeal having
been presented, or an appeal has been presented but has been dismissed, it
shall be lawful for either party to the marriage to marry again:

Provided that it shall not be lawful for the respective
parties to marry again unless at the date of such marriage at least one year
has elapsed from the date of the decree in the court of the first instance.
